Abstract: | In rats carbaryl undergoes extensive biotransformation involving both albumin-mediated hydrolysis and cytochrome P-450-mediated metabolism; studies have suggested that approximately one-half of a carbaryl dose is hydrolysed and one-half is metabolized. Fluosol is known to be an inducer of cytochrome P-450, and Fluosol haemodilution reduces plasma albumin concentrations. The disposition of carbaryl was, therefore, determined in rats for 72 h after 40 mL kg-1 haemodilution with Fluosol or normal saline (0.9% NaCl). Volumes of distribution were significantly reduced after saline haemodilution for 72 h but only at 48 h after Fluosol haemodilution. Fluosol and saline haemodilution had little influence on carbaryl total body clearance (CL). These results indicate that both hepatic and non-hepatic clearance pathways were not influenced by the haemodiluents or the haemodilution procedure. |
